Buggy code:
public class ManagePanel extends JPanel { public ManagePanel ( PluginManager window ) { } public void update ( ) { } private JCheckBox hideLibraries ; private JTable table ; private ManagePanel . PluginTableModel pluginModel ; private PluginManager window ; private int showListConfirm ( String name , String [ ] args , Vector listModel ) { } class Entry { static final String ERROR = "error" ; static final String LOADED = "loaded" ; static final String NOT_LOADED = "not-loaded" ; String status ; String jar ; String clazz ; String name ; String version ; String author ; String docs ; List jars ; Entry ( String jar ) { } Entry ( PluginJAR jar ) { } } class PluginTableModel extends AbstractTableModel { private List entries ; private int sortType = ManagePanel . EntryCompare . NAME ; public PluginTableModel ( ) { } public int getColumnCount ( ) { } public Class getColumnClass ( int columnIndex ) { } public String getColumnName ( int column ) { } public ManagePanel . Entry getEntry ( int rowIndex ) { } public int getRowCount ( ) { } public Object getValueAt ( int rowIndex , int columnIndex ) { ManagePanel . Entry entry = ( ( ManagePanel .

Entry e1 , ManagePanel . Entry e2 ) { } } class HeaderMouseHandler extends MouseAdapter { public void mouseClicked ( MouseEvent evt ) { } } }

Fix:
return new Boolean ( ( ! ( entry . status . equals ( ManagePanel . Entry . NOT_LOADED ) ) ) ) ;
